Validation of the "ApneaScan" Algorithm for the Detection of Sleep Disordered Breathing in Chronic Heart Failure

Official Title ICMJE

Validation of the "ApneaScan" Algorithm for the Detection of Sleep Disordered Breathing in Patients With Stable Symptomatic Chronic Heart Failure

Brief Summary

A prospective observational multi-centre study for the validation of the ApneaScan algorithm (integrated in ICD devices (with or without cardiac resynchronization therapy function) of the "Incepta" series for the screening of sleep disordered breathing in patients with stable symptomatic chronic heart failure, using portable polygraphy monitoring device ("Embletta Gold") as reference for the Apnea-Hypopnea-Index (AHI).

Secondary objectives are the detection of severe sleep disordered breathing in patients with clinically indicated in-laboratory polysomnography, as well as correlations of the AHI detected by ApneaScan with other clinical endpoints like mortality, hospitalization, atrial fibrillation and ventricular arrhythmia.

Eligibility Criteria ICMJE

Inclusion Criteria:

Age over 18 years

Patient´s written informed consent

Patients with a cardiac rhythm management device (ICD with or without cardiac resynchronization therapy function) of the "Incepta" series (including the ApneaScan algorithm) already implanted for at least 8 weeks (corresponding to the duration of the leads´ healing process); in order to standardize the enrollment period, inclusion should be effected between the first (the earliest 8 weeks after implantation) and the second routine control of ICD-function (the latest 9 months after implantation)

Stable symptomatic chronic heart failure for either ischemic or non-ischemic reason (moderately to severely impaired systolic left ventricular function with NYHA-class II to III) under optimal pharmacological treatment (according to guidelines 2012 of the European Society of Cardiology)
